Description
BACKGROUND OF THE INVENTION
This invention relates to an apparatus for discriminating paper
money which has the ability of discriminating the authenticity of
the paper money or the denomination of the same, and of receiving
said money as in a stacked state.
There are used in various sorts of vending machines some kind of
paper money discriminating apparatus which discriminates the
genuineness or denomination of paper money and further receives the
paper money discriminated as genuine notes in a stacked state. In
such apparatus, there are heretofore inconveniences because of the
paper money-receiving part taking the form of a box and being
attached undetachably to the main body of the apparatus with the
result that it is necessary to remove the paper money by grasping
the received ones directly by hand, when the paper money sometimes
are liable to scatter. Under these circumstances, the inventors of
this invention have proposed by United States patent application
Ser. No. 817,587 pending 311 an apparatus for discriminating paper
money with a stacking means which is able to solve the
controversial point as mentioned above and enables the collecting
operation to be rapid and efficient by forming the paper
money-receiving stacker box in what is called a detachable
cartridge type.
And yet, since such a stacker box as mentioned above has a
relatively large opening part for inserting paper money into the
interior, the received paper money are within a range of the
taker's eye at the time of collecting and consequently can be
easily taken out, which threatens to induce dishonest pilferage
when collecting.
SUMMARY OF THE INVENTION
An object of this invention is to provide an apparatus for
discriminating paper money with a stacking means which has the
ability to solve the controversial point as mentioned above on the
basis of having a covering plate to shut the opening part and a
locking means to lock the covering plate in a shut state
thereof.

The main body 2 of a apparatus is possessed of the base frame 20.
As shown in FIGS. 2 and 6, this base frame 20 raises erectly the
upper plate part 24 narrow in width on the middle part of the lower
plate part 23, and is possessed of plates 21, forming a reverse
T-shape and a frontal plate 25 joining the front ends of the
above-mentioned upper plate part 24. On the other hand, at the
lower ends of the side plates 21, joining pieces 26 and 27 are
spanned across. Beneath the joining piece 26 is fitted the fitting
piece 29. Further, on the upper end of the frontal plate 25 is
formed an upper plate 30 through bending. On this upper plate 30 is
raised erectly a fitting piece 31. The frontal cover 22 being
fitted to the lower end part of the base frame 20 constitutes a
square cylinder shape surrounding the frontal end parts of the
above-mentioned lower plate parts 23 and is fixed on the
above-mentioned fitting piece 29 and on the front face of the
frontal plate 25 by a flange 33 being formed on the rear end. The
opening part on the front face of the frontal cover 22 forms an
inserting port 17 through which the paper moneys B are to be
inserted. This inserting part 17 is provided with an opening or
shutting lid 34 which can be sprung up.
Further as shown in FIGS. 3 and 4, to the base frame 20 are fitted
an upper block piece 39 and lower block piece 40 between the lower
plate parts 23.
There is provided on lower block piece 40 at the rear fringe of the
basal part 41 which is nearly the same in depth as the
above-mentioned lower plate part 23 a projecting part 42, of which
the form of a side face is L-shaped. The front end part of the
above-mentioned basal part 41 is inserted into the frontal cover
22, and its front end impinges against the lower end part of the
opening and shutting lid 34. The upper face of the basal part 41
forms at the rear end of its horizontal plane a smooth circular
arced face continuing to the vertical front face of the projecting
part 42, and also forms at its front end a guiding part 43 being
composed of an inclined surface hanging down forward.
The upper block piece 39 is arranged spacing an almost fined
interval above the basal part 41 of the above-mentioned lower block
piece 40. This interval continues to the above-mentioned inserting
part 17 and forms the lower passage 4A through which the paper
monies B are transferred. Accordingly, this lower passage 4A is
provided from before in order with the guiding part 43, the
horizontal part, the circular arced part, and the vertical part,
and guides the paper money B being inserted horizontally in an
upward state as they are.
The upper and lower block pieces 39 and 40 are formed with a
hollow-shape. The lower block piece 40 is fitted up extractably in
the backward direction when the projecting piece 46 which is
provided protuberantly on the inner face of the above-mentioned
side plate 21 engages the groove 45 which is formed on the front
fringe of the side face and further when the projecting piece 48
which is provided protuberantly on the above-mentioned side face
engages the groove 47 which is formed on the rear fringe of the
side plate 21. Besides, the lower block piece 40 is fixed on the
base frame 20 when the hook 44 which is encouraged by a spring
being fitted on the side face hooks the engaging part 28 where the
rear fringe of the side plate 21 is notched in the form of a
L-shape.
To the side plates 21 of the above-mentioned base frame 20 are
attached guide fittings 99. The guide fitting 99 takes the form of
an L-shaped cross section which forms orthogonally an inward-facing
guide piece 100 on the rear end of the fitting piece to be fixed on
the rear end part of the upper plate part 24 over the side plates
21. The guide piece 100 is provided both on the nearly middle part
and the lower end part with the keep tool 12 which is possessed of
the circular arced projecting part 101 being composed of leaf
springs and protruding in the forward direction. Further, there is
formed on a lower end of the guide piece 100 the guiding part being
bent backward.
There is fitted in the interior of the base frame 20 an inner frame
19. This inner frame 19 takes the form of a U-shaped cross section
by forming side plates 50 on both side fringes of the frontal plate
49 which is fixed on the above-mentioned frontal plate 25. On the
other hand the lower end parts of the side plates 50, constitute
inserting parts 55, to be inserted into the rear end part of the
above-mentioned upper block piece 39.
The transferring tool 5 consists of a first transferring tool 57
which is disposed in a inner frame 19 and driven by the
transferring motor M1, and the second transferring tool 59 which is
arranged on the upper block piece 39 and the lower block piece 40
and which is driven by the first transferring tool 57.
First transferring tool 57 fixes fast the rotary bodies 63 and 64
on the both ends of the supporting shafts 61, 62 piercing through
both the upper end part of the side plate 50 and the inserting part
55, and is wound round with endless link cords 65, being made up of
timing belts between the rotary bodies 63 and 64. The supporting
shaft 61 forms the gear unit 67 together with the worm wheel, the
worm gear and the like, and makes a retardative revolution by the
rotation of the transferring motor M1. Therefore, the
running-backward line of the endless link cord 65 moves up and down
owing to the normal or reverse rotation of the transferring motor
M1. In this connection, a rotary encoder E is provided on the
rotary shaft 69 which projects to the upper end of the gear unit 67
and which rotates synchronously with the supporting shaft 61.
The second transferring tool 59 fits up with the rotary bodies 77
and 79 on both ends of the supporting shafts 75, 76 piercing
through the basal part 41 of the lower block piece 40, while the
endless link cords 90 being made up of the timing belts are wound
round between the rotary bodies 77, 79. The supporting shafts 75,
76 can move up and down through the long holes 91 . . . which are
provided on the side plates of the lower block piece 40 and which
extend in the upward and downward direction, and are encouraged by
the spring 93 being disposed at both ends of the supporting pin 92
which is spanned between the above-mentioned side plates in the
middles of the supporting shafts 75, 76. On the other hand, the
receiving rollers 95, are provided aligning with the upper part of
the rotary body 77.
The receiving rollers 95 are fixed fast on both ends of the
supporting shaft 96 which penetrate through the long hole of the
front end part of the upper block piece 39 and are encouraged
downward by the spring 94. Accordingly, the running-upward line of
the endless link cord 90 impinges upon both the under face of the
receiving roller 95 and the under face of the endless link cord 65
of the first transferring tool 57. Through this impingement, the
running-upward line of the endless link cord 90 is located in the
center between the up-and-down movement through the above-mentioned
under passage 4A, while the running-backward line of the endless
link cord 65 is located in the center between the front and the
rear of the vertical part of the passage 4A.
Further, the running-backward line of the endless link cord 65 and
the guiding piece 100 face each other spacing a small gap in
between; this small gap continues to the above-mentioned lower
passage 4A, and constitutes the upper passage 4B forming the
above-mentioned passage 4 together with the passage 4A. On the
other hand, the projecting parts 101 of the keep tool 102 impinge
against the above-mentioned running-backward line, while the
guiding pieces 100 guide both side parts of the paper money B and
also support vertically the paper money B together with the endless
link cord 65 in between. In this connection, there is formed
between and by the inner ends of the guiding pieces 100 the
above-mentioned stuffing part 7 which makes the reverse face of the
above-mentioned paper money B exposed.
In consequence, while supporting from inside and outside both side
fringes of the paper money B being inserted into the inserting port
17 in a state of being developed, the transferring tool 5 can
transfer them up to the stuffing part 7 in a state of being
developed as they are.
There is disposed in the center of the above-mentioned passage 4
the sensor 6 for discriminating a paper money. In this example, a
sensor 6 is the magnetic head having a pair of magnetoresistance
elements and a magnet for bias, and is provided on the
above-mentioned upper block piece 39 turning downward.
Further, there is additionally provided on a sensor 6 the pinch
roller 70. This pinch roller 70 is attached to a supporting shaft
71 which is spanned movably up-and-down on the side plate of the
lower block piece 40, is encouraged upward by a spring 72 being
attached to the above-mentioned supporting shaft 75, and impinges
softly upon the sensor 6. On the other hand, there is disposed on
the front end of a passage 4A the detector 80 which is made up of a
photosensor and which detects the insertion of the paper money B.
Further, there are arranged at the circular arced part of the
passage 4A lever pieces 82 which operate the detector 81 by
impinging against the transferred paper money B so as to tilt, and
which return to their original positions soon after the paper money
B has passed through to prevent the returning back of the paper
money B.
In addition, there are provided on the above-mentioned stuffing
part 7 of the passage 4 the sending tools 9.
As shown in FIGS. 6 to 8, the sending tool 9 forms the bearing
pieces 127 in the backward direction on the inner end of the basal
part 125 being made up of bent piece of crankshaped cross section,
and pivots the long roller 126 in between parallel to the passage
4B. Further, there are provided protuberantly turning backward on
the outer end of the basal part 125 projecting pieces 130 being
pinned on the bearing pieces 129 on the side plate 50 of the
above-mentioned inner frame 19 above and below. Consequently, as
shown in FIGS. 6 to 8, the sending tool 9 is able to swivel around
the pivoting point which is located in the vicinity and in front of
both side ends of the passage 4B. Through this swivelling, the
roller 126 can swivel through the passage 4 from front to rear and
through the stuffing part 7 up to the back of the above-mentioned
guiding piece 100.
On the other hand, there is attached to the inner frame 19 a
swivelling tool 36 to swivel the sending tool 9.
A swivelling tool 36 has sending motor M2 and the substantially the
same gear unit 131 as the above-mentioned gear unit 67, and the
disc-shaped cam pieces 132 are eccentrically fixed on both ends of
the output shaft 133 projecting to both sides of the gear unit 131
and piercing through the side plates 50 while in the center of the
cam piece 132 the pin 134 is protuberantly provided making
eccentric the above-mentioned output shaft 133. There is pivoted on
the pin 134 a sliding piece 137 floatingly pierced through the
slide shaft 136 extending upward and downward. The upper and lower
ends of the slide shaft 136 are connected through the arms 140
being connected by joining piece 139 to the supporting pieces 142
projecting to the frontal face of the above-mentioned basal part
125. There is spanned between the basal part 125 and the pin
projecting from the front fringe part of the side plate 50 a spring
144. Consequently the sending tools 9 can swivel when the sliding
piece 137 describes a circular motion by the rotation of the cam
piece 132, and the slide shaft 136 pushes the basal part 125
backward through the arm piece 140.
On the above-mentioned main body 2 of the discriminating apparatus
1, there is formed the hooking part 13 for fitting up the stacker
box 3. In this example, the hooking part 13 has an L-shaped notch
provided on the lower fringes of the hooks 146 provided
protuberantly turning backward on the upper end part of the side
plates 21 of the base frame 20, and the rear fringe thereof is made
circular arced. On the side face of the lower block piece 40
exposed by notching the upper corner part of the rear end of the
lower plate part 23 of the side plate 21 in the form of a L-shape,
there are provided hooking grooves 147 which extend upward and
downward, but open at the upper end, and are arranged at the lower
end with a receiving piece 150 being made up leaf springs.
The base box 10 of an stacker box 3 is fitted up with the upper
plate 10 on the U-shaped frame having the rear plate 104 and the
side plates 105, and also the lower plate 107 being capable of
opening and shutting.
The rear plate 104 is made up of the rectangular flat plate body
slightly larger than the paper money B, whose lower fringe is
provided with the U-shaped notched part 109.
The side plate 105 is formed on the frontal fringes in such a
manner that the narrow frontal pieces 115 may face each other
turning inward, on the one hand, and on the other, there is
provided on the lower fringe a projecting piece 111 being
protuberantly provided with a hooking pin 110 in the inner face
which is to be inserted in the above-mentioned hooking groove 147.
There are provided in the inner face of the middle part of the side
plate 105 continuous guiding grooves 122 extending in the forward
and backward direction. By inserting into this guiding groove 122
the projecting piece 121 protuberantly provided on both side
fringes of the receiving plate 116 which is made up of the
rectangular flat plate body arranged parallel to the rear plate
104, the receiving plate 116 is supported movably at either end.
What is more, this receiving plate 116 is encouraged forward by the
spring 117 being arranged between itself and the rear plate 104,
where both side fringes thereof impinge against the above-mentioned
frontal pieces 115. Further, there is provided a notched part 109
also on the lower fringe of the receiving plate 116.
The lower plate 107 raises erectly on both side fringes of the side
pieces 112 which are in line with each of the outer faces of the
side plate 105. The upper front end part of the said side piece 112
is pinned on the above-mentioned side plate 105, and is brought to
a stop being left open as it is when the projecting part turning
outward of the lock piece 114 made up of a spring plate attached to
the side plate 105 engages the hole part 113 provided in the inner
face of the rear end part of the side piece 112.
As shown in FIG. 11, the upper plate 106 is spanned over to the
extension part 105A of the upper end of the side plate 105, which
constitutes in this example the frame of the above-mentioned
locking tool 15.
The base box 10 can be inserted in midway between the
above-mentioned hooks 146 by inserting the hooking pin 110 into the
hooking groove 147 to swing forward, when the base box 10 can be
attached to the main body 2 of the apparatus through the engagement
of the hanging part being made up of fan-shaped projecting parts
which are formed on the side faces of the base box 10 with the
hooking part 13 of the above-mentioned hook 146. In this
connection, the base box 10 can be detached by being pushed down
against the receiving piece 150 and swinging backward.
Being attendant on the attachment of the base box 10, the
above-mentioned opening part 11 which is formed between the frontal
piece 115 on the front of the base box 10 comes to surround the
stuffing part 7 of the above-mentioned passage 4.
In consequence, as shown in FIG. 7 by the alternate long and two
short dash line, the above-mentioned sending tools 9 send out the
paper money B through the stuffing part 7 rearward, on the one
hand, and on the other, the roller 126 pushes the paper money B
against the receiving plate 116, and holds the paper money B with
the receiving plate 116 between. Further as shown in FIG. 8, a
sending tool 9 swings at the maximum angle in a state where the cam
piece 132 rotates a half turn, while the roller 126 turns about to
the rear of the frontal piece 115 while spreading both side parts
of the paper money B. Consequently, the sending tool 9 in
cooperation with the roller 126 tucks paper monies B through the
above-mentioned opening part 11 into the stacker box 3. Further,
when the cam piece 132 swings to make one revolution, then a
sending tool 9 swings in the reverse direction. As the result, the
receiving plate 116 shifts forward in accompaniment with the roller
126 and holds the paper money B between that receiving plate 9 and
the frontal pieces 115. In this way, the paper monies B are
received in tiers and within the stacker box 3.
The above-mentioned opening part 11 is closed by the covering plate
14. As shown in FIG. 9, this covering plate 14 is a rectangular
flat plate body, which is to be inserted between the quiding pieces
151 being raised erectly from the upper end of the above-mentioned
frontal piece 115 and the front fringe of the upper plate 106. When
being inserted along the rear face of the frontal piece 115, the
lower end of this covering plate is over the front fringe of the
above-mentioned lower plate 107. Accordingly, the covering plate 14
shuts the opening part 11 and prevents the lower plate 107 to be
left open on the basis of a state where the covering plate 14
impinges upon the front fringe of the lower plate 107.
As shown in FIGS. 9 to 11, the locking tool 15 is equipped with a
sliding tool 154 the head of which engages through forward movement
with the hooking holes 153 being fitted on the upper end part of
the covering plate 14 and which thereby makes it impossible to draw
out the covering plate 14 in the state of being closed; the stopper
tool 155 makes it impossible for the sliding tool 154 being in a
state of forward movement to move backward; and the releasing tool
156 which swings by the key K to release the stopper tool 155 from
the hooked state.
As shown in FIG. 11, the sliding tool 154 is provided with the
horizontal upper piece 160 and a side pieces 159 extending in the
forward and backward direction, and takes the form of a
turning-downward U-shaped cross section. The front end of the side
piece 159 has a tapered face of an inclined angle of about
90.degree., and forms a fitting part 161 which fits into the
above-mentioned hooking hole 153 of the covering plate 14. Further,
there are provided on the front end part and the rear end part of
the side plate 159 long holes 162, 163. On the other hand, there
are raised erectly on the above-mentioned upper plate 106 at both
sides in front and behind the standing pieces 164, and 165 along
the inner face of the side pieces 159. The sliding tool 154 is able
to slide forward and backward both by the slide shaft 166 passing
through the above-mentioned long holes 162 and being spanned
between the standing pieces 164 and by the slide pin 167 passing
through the long hole 163 and fixing the inner end on the standing
piece 165. Besides, there is provided on a under face of the side
piece 159 the stair-shaped notch being provided with a hooking part
171 made up of a notched part of comparatively small height and an
escape part 172 being made up of a notched part of comparatively
large height and being set up jointly at the back of the former.
Further, there is formed by bending on the upper fringe of the
escape part 172 projecting pieces 173 which project inward, while
the projecting piece 174 which projects outward is protuberantly
provided at the back of the above-mentioned escape part 172 of the
under fringes of the side piece 159. What is more, there is
protuberantly provided on the rear end part of the upper fringe of
the side piece 159 a turning-outward spring hanger bracket 176, on
which one end of the spring 177 attached to the above-mentioned
slide pin 167 is hooked and encourages the slide tool 154
forward.
In this example, the sliding tool 154 is hindered from forward
movement by the stopper arm 157.
The stopper arm 157 is set up swingably between the standing pieces
164 through the above-mentioned slide shaft 166 to hook the front
fringe of the above-mentioned projecting piece 173 using rear
fringe thereof, and has a press part 179 and arm parts 190. The
press part 179 projects forward beyond the inserted plane of the
covering plate 14 to impinge against the covering plate 14 at the
inserting time. The arm parts 190 rise erectly on both side fringes
of the press part 179, and let the above-mentioned sliding shaft
166 pierce through the frontal end part thereof. Further, this
stopper arm 157 is encouraged upward by the spring 191 being fitted
on the sliding shaft 166. Further, there is provided on the
above-mentioned upper piece 162 an escape hole 192 of the arm part
190.
The above-mentioned hooking state is released by the rear end of
the arm part 190 being raised up at the inserting time of the
covering plate 14.
The above-mentioned stopper tool 155 comprises arm parts 194 which
are swingably fitted with a slide pin 167 on the standing piece 165
at the outer side of the above-mentioned side piece 159, and the
joining piece 195 which is spanned between the front end of the
under fringes of the arm parts 194 to interconnect them. On the
other hand, there is protuberantly provided on a rear end of the
arm part 194 the spring hanger bracket 196, on which the other end
of the above-mentioned spring 177 is hooked. In consequence, the
arm part 194 is encouraged upward at the front end by the spring
177, whereby the under face of the projecting piece 174 impinges
upon the upper face of the head part of the arm part 194 at the
going-back position of the sliding tool 154. On the other hand, the
projecting piece 174 moves forward over the head of the arm part
194 in concert with the forward shifting of the sliding tool 154,
so that arm part 194 raises up and thereby hooks the rear end of
the projecting piece 174 at the front fringe of the arm part 194 to
prevent the backward movement of the sliding tool 154.
The above-mentioned releasing tool 156 consists both of a main body
201 for locking which is clamped with screws on the fitting piece
199 being raised erectly on the rear fringe of the upper plate 105
and which is provided with rotary shaft 200 being put in rotation
only by the corresponding key K, and of the key cam 202 which is
fixed on the above rotary shaft 200 and which pushes down the
joining piece 195 of the above-mentioned stopper tool 155 in
accompaniment with the rotation of the above rotary shaft 200.
In this example, the locking tool 15 is provided with locking shaft
204 which makes it impossible to remove the stacker box 3 at the
time of releasing the opening part 11 in cooperation with the
above-mentioned sliding tool 154.
The locking shaft 204 is of a round bar form, and penetrates
through the lower part of the hooking part 171 between the upper
plate 106 and the sliding tool 154, the both end of which project
from the hole parts 205 being provided on the above-mentioned
extension parts 105A of the side plates 105 of the base box 10 and
that to both sides of the base box 10 at the upper part of the
above-mentioned hooking part 12. In this connection, the locking
shaft 204 is encouraged forward by spring 206 being fitted on the
inner face of the above-mentioned extension part 105A. Further,
there is provided on the upper part of the base box 10 the upper
cover 207 covering the locking tool 15 inclusive of the
above-mentioned projective parts of the both ends of the locking
shaft 204.
Consequently, at the time of setting up the stacker box 3 on the
main body 2 of the apparatus, the base box 10 is inserted between
the hooks 146 by inserting the hooking pins 110 into the hooking
grooves 147 and thereby tilting the base box 10 forward, as
mentioned above. At this time, as shown in FIG. 12, the
above-mentioned locking shaft 204 is located at the front end part
of the hole part 205 while being encouraged by the spring 206 and
impinges upon the under face of the hooking part 171. And as shown
in FIG. 13, the locking shaft 204 is pushed by the hook 146 and
shifts to the rear end part of the hole part 205, when the hook 146
engages with the hanging part 12, as shown in FIG. 14, then the
stacker box 3 is encouraged upward by the receiving piece 150 and
goes up. In this state, the locking shaft 204 is inserted between
the hook 146 and the hooking part 171 of the sliding tool 154 with
the help of the spring 206.
In this way, the hook 146 is hooked between the hanging part 12 and
the locking shaft 204, thereby making impossible the up-and-down
movement of the stacker box 3 and the removal of the main body of
the apparatus as well.
When required to remove the stacker box 3, the opening part 11 must
be closed by the use of the covering plate 14. As shown in FIG. 15,
by inserting the covering plate 14 between the guiding pieces 151
to close the opening part 11, the stopper arm 157 swings to allow
the forward movement of the sliding tool 154, as mentioned above,
whereby the fitting part 161 of the sliding tool 154 having moved
forward fits in the hooking hole 123 to make impossible the removal
of the covering plate 14. On the other hand, by the forward
movement of the sliding tool 154, the escape part 172 goes ahead to
the upper part of the locking shaft 204, whereby the locking shaft
204 becomes able to shift upward. In consequence, by pushing down
the stacker box 3 against the above-mentioned receiving piece 150,
the hook 146 can push up the locking shaft 204, thereby releasing
the engagement of the hooking part 13 with the hanging part 12 and
the stacker box 3 thus being able to be removed. As shown in FIG.
9, the press part 179 swings at the time of inserting the covering
plate 14, presses down the upper end part of the paper money B . .
. having been received within the stacker box 3, and makes easy the
insertion of the covering plate 14.
Accordingly, since the stacker box 3 is closed at its opening part
11 by the covering plate 14 at the time of releasing the
above-mentioned engagement, the paper monies B . . . having been
received within the interior of the stacker box 3 are invisible to
the person's sight and cannot to be taken out.
In order to take out from the detached stacker box 3 the paper
monies B . . . having been received in the interior, the key cam
202 must be made to swing by rotating while inserting the key K
into the key hole of the main body 201 for locking, and therewith
to push down the joining piece 195 of the stopper tool 155. In a
state of the sliding tool 154 being possible to go back, the bottom
fringe of the hooking hole 153 shifts on the under tapered face of
the fitting part 161 by forcedly pulling out the covering plate 14
to cause the sliding tool 154 to go back. Then it becomes possible
easily to extract the covering plate 14. Such a state is shown in
FIG. 9. By the covering plate 14 being pulled out, the stopper arm
157 is raised up through the spring 191, and the rear end of the
arm part 190 hooks the projecting piece 173, as mentioned above,
and thus the forward movement of the sliding tool 154 is prevented.
With the release of the opening part 11 the lower plate 107 also
becomes releasable, as the result of which it is possible to pull
out the paper monies B . . . having been received out of the
opening part of the bottom face of the base box 10 in a state of
lying in a stack as they are.
The locking tool 15 in this example makes impossible the removal of
the stacker box 3 from the main body 2 of the apparatus in the case
of the state of the opening part 11 being released, on the one
hand, and on the other, the very removal of the stacker box 3 from
the main body 2 of the apparatus is enabled by shutting the opening
part 11 by the covering plate 14.
FIGS. 16 and 17 further show other examples of the stacker box 3
where the covering plate 14 is to be housed in the interior of the
stacker box 3 at the time of the opening part 11 being released.
The covering plate 14 is pulled out from between the back plate 104
and the parting strip 213 being disposed in front of the plate 104,
by the sprocket 212 being turned round using the knob 211 provided
on the side face of the side plate 105, which then shuts the
opening part 11. What is more, in this shutting state, the sliding
tool 154 goes ahead, the fitting part 161 fits into the hooking
hole 153, and in this way the covering plate 14 is locked. To
release this locked covering plate 14, the key cam 202 of the
releasing tool 156 rotates, compresses the pushing piece 214 being
raised erectly on the sliding tool 154 to make it go back, and then
the knob 211 is forced to be turned.
In front of the main body of the apparatus, there is provided a
printed base plate 83 of the control circuit being covered over by
the cover 84.
This control circuit compares a pattern signal S2 which is acquired
from the output of the sensor 6 scanning the pattern being printed
on a paper money B using the magnetic ink along the scanning route
SCO extending in the longitudinal direction of the paper money B,
with the standard pattern signal R, on the basis of which the
genuineness of the paper money and the denomination is
discriminated.
The control circuit comprises a microprocessor, ROM, RAM, an
interface, and others, and is what is called a micon which works
under program stored previously in ROM. To the interface are
connected the above-mentioned sensor 6 through the an A/D
converter, and also the detectors 80, 81, the rotary encoder E, the
transferring motor 1, the sending motor M2, the alarm, and
others.
Description will be now directed to the behavior of the control
circuit with the reference to FIG. 18 to 22.
By inserting the paper money B in the passage 4, the detector 80
detects the paper money B and the transferring motor M1 rotates,
then that paper money B is fed into the interior of the passage 4
with the aide of the transferring tool 5, as mentioned above. The
rotary encoder E outputs a timing signal for data sampling every
0.2 mm on the printed surface of the paper money B in this example.
The above-mentioned sensor 6 has an electrical property much like a
magnetic head having a very wide gap, and outputs an analog signal
S1 containing relatively wide pulses P1-P7 corresponding to the
bordering lines 221 of the paper money B, the portrait part 222,
and the sum-indicating part 223.
This analog signal S1 is converted by the A/D converter into, for
example a, word of 8 bits sampled by the microprocessor every
timing signal, thus is once stored within RAM. And the
microprocessor processes the above-mentioned words stored within
RAM and substracts the noise level from the value expressed by each
word in order to eliminate the influence which noise has upon the
discrimination of the paper money, and replaces the subtracted data
with the original data. This data string is regarded as the
above-mentioned pattern signal S2 for discriminating the paper
money. This pattern signal S2 is compared with the standard pattern
signal R stored previously within ROM.
The standard pattern signal R is one that prescribes the tolerance,
in this example, the minimum of the amplitude centering around the
reference level LO of the pattern signal S2, and that contains the
standard pattern signals, for example, R1-R18 of 18 (=3 scanning
routes .times.3 denominations .times.2 scanning directions) in
total in the case of being scanned the above-mentioned scanning
route SCO in the center and the scanning routes SC1, SC2 slightly
shifting from both sides of the former with every denomination of
the paper money to be discriminated (1 dollar, 5 dollars, 10
dollars) from both sides. The standard pattern signals R1-R18 are
each compared with the pattern signal S2 in coincidence and
non-coincidence.
The comparison is done in such a manner that the amplitude in the
corresponding position of the pattern signal S2 and each of the
standard pattern signals Rn (n=1 to 18) are compared. When the
amplitude of the pattern signal S2 within the tolerance, in this
example, is larger, it is considered as coincidence, but when the
amplitudes of the standard pattern signals Rn are out of the
tolerance, they are considered as non-coincidence. When the number
of times of this non-coincidence is less than the value Dn
predetermined for the then standard pattern signals Rn, it is
decided that the standard pattern signals Rn coincide with the
pattern signal S2.
The comparison consists in comparing the amplitudes in the
corresponding positions of the pattern signal S2 and the standard
pattern signals Rn. This corresponding position is decided by
shifting word by word, for example, up to the 8 words maximum, at
both sides of the reference position centering around, for example,
the reference state obtained while allowing the above-mentioned
bordering line approximately to coincide. In this way, the same
comparison as mentioned above is done at each shifting state. To
illustrate the above typically, FIG. 20 shows the above-mentioned
reference state, which is an example to be judged that in the
pattern signal S2, only the 11th word from left in the figure is
led to non-coincidence, but the pattern signal S2 and the standard
pattern signals Rn coincide each with other. FIG. 21 shows the
state of having shifted the standard pattern signals Rn by 1 word
to the right against the pattern signal S2 where the number of
times of non-coincidence becomes 5, which is judged that the
pattern signal S2 does not coincide with the standard pattern
signals Rn. Similarly, FIG. 22 shows the state where one word has
been shifted to the left. This case also is judged as
non-coincidence in the same manner as the above-mentioned.
Such a way of comparing by the pattern signal S2 is conducted on
each of the standard pattern signals R1-R18. On the basis of the
denomination of the coinciding standard pattern signals Rn, the
genuineness of the paper money B and the discrimination of the
denomination are carried out. In this connection, in the case of
coincidences covering plural denominations or in the case where
there are no coinciding denominations, it is judged that those are
false paper monies or indiscriminable notes.
Therefore, the control circuit is able to make the discrimination
regardless of the inserting direction of the paper money B being
normal or reverse.
Further, it is able to compare the pattern signal S2 and the
standard pattern signals Rn under the condition wherein the
above-mentioned reference positions are made to coincide mutually
and the conditions wherein those reference positions are made to
laterally shift mutually spacing a small distance, in this example,
by 0.2 mm on the paper money B, so that the discrimination is
possible to be performed with high precision even when there occurs
a discrepancy owing to the divergence in the sending direction of
the paper money B or the tilt of the currency in the interior of
the passage 4.
As has been hitherto described, the paper money B being inserted
into the passage 4 screens the detector 80 and at the same time
drives the transferring motor M1. Thereby, the paper money B is fed
into the inner part of the passage 4 by means of the first
transferring tool 57 and passes through under the sensor 6. On the
other hand, as mentioned above, the sensor 6 reads the
discriminating pattern printed on the paper money B and thereby
discriminates the genuineness and the denomination. The paper money
B being discriminated as a genuine note is guided by the first
transferring tool 57 to the inner part of the passage 4B and stops
there. On the other hand, the paper money B has both end parts
being held between the first transferring tool 57 and the guiding
piece 100, and its reverse surface is exposed by the stuffing part
7. The control circuit detects by the detector 81 that the rear end
of the paper money B has passed through the lever piece 82, and
stops the first transferring tool 57. With the stoppage of the
first transferring tool 57, the swinging tool 36 goes into action,
while the sending tool 5 stuffs the paper money B through both the
stuffing part 7 and the opening part 11 into the stacker box 3, as
mentioned above, and then the control circuit outputs what is
called a vending signal to the apparatus such as a vending
machine.
When the paper money B is impossible to be discriminated, then the
transferring motor M1 is thrown into reverse, so that the paper
money B is sent back toward the inserting port 17, simultaneously
an alarm functions to give an alarm.
The sending tool 9 can send out smoothly the paper money by virtue
of the rotatability of the roller 126, and further is able to push
the paper money B against the receiving plate 116 while spreading
out surely even when it is a used and worn-out paper monies B.
Therefore, without allowing the paper monies to pile one upon other
when being folded as they are, the paper monies B are received
regularly in piles within the stacker box 3.
Incidentally, there can be utilized in the apparatus for
discriminating paper money stacking the same 1 according to the
invention such a sort as a photosensor other than the magnetic
sensor in the capacity of the sensor 6. Also the transferring tool
5 may be formed by a single transferring tool without using the
first and second transferring tools 57, 59. Further the
transferring tool 5 may be also formed by such as a couple of
driving rollers and keep rollers without using endless link cords.
On the other hand, the swinging tool 36 can be made using gears or
cams of a certain-kinds even when those are able to swing the
transferring tool 9. The apparatus for discriminating paper money
and stacking the same according to the invention can be modified
into various embodiments, for example, by forming so as to
discharge undiscriminatable paper money to the other end of the
passage 4.
As mentioned above, since the apparatus for discriminating paper
money and stacking the same according to the invention is such a
one that provides a locking tool which locks the covering plate to
shut the opening part of the stacker box and that in a shutting
state of the covering plate as it is at the time of removing the
stacker box, the received paper money can be quickly collected
together with the stacker box, thereby being able to promote the
efficiency of the collecting operation of the paper money, the
pilferages of the money can be prevented, the degree of safety is
elevated, and such like. Many effects being brought about by this
invention are immeasurable.
